4 Claims. (01. 167- 3) This invention relates to Vaporizers and more especially to a device ofrthat character adapted for use in connection with an electric lamp bulb.

One of the important objects of the invention is the provision of a simple, eflicient and inex pensive vaporizing device for impregnating the air with a vapor having medicinal, disinfecting or perfuming qualities.

Another object is the provision of a device suitable for mounting on anelectric lamp bulb so that the heat radiated fromthe lamp when lighted may bring about a rapid vaporization of the material carried by the device. A further object of the invention is the provision of a device made of paper or other cheap absorbent material adapted to be impregnated with a vaporizable, material and which may be discarded and thrown away after'use. h An additional object is the provision of a device which when mounted on the electric lamp bulb will not diminish the light emitted from the lamp nor detract from its appearance.

Other objects of the invention will be more specifically set forth and described hereinafter.

My invention contemplates a vaporizing device made in any suitable form comprising a body portion of paper or other suitable absorbentmaterial impregnated or saturated with any suitable vaporizable compound or substance. In its simplest form, the body portion comprises a disk either plain or fluted made from suitable absorbent material and provided with a central opening or with other means for mounting it on or attaching it to an electric lamp so that the heat from the lamp may expedite the vaporizing of the substance carried by the body portion. It is apparent that the body portion may be made in many diiferent forms and may comprise one or more disks fluted in various ways or may be made in square or polygonal form.

In the accompanying drawing illustrating the invention, Figure 1 is a view in perspective of an electric lamp bulb having mounted thereon a vaporizing device made in accordance with my invention; Fig. 2 is a plan view of the same looking downwardly in Figure 1 and Fig. 3 is a view in perspective of a simple plain disk form of device.

'In Figures 1 and 2 of the drawing is shown the preferred form of vaporizing device in which the body portion 10 is in the form of a disk having a central opening 11 for receiving the threaded shank 12 of an electric lamp bulb 13. The disk is fluted radially which causes it to assume the shape of a small lamp shade. The number or menthol and if the device is to be used for of flutes 15 may be varied to produce a variety. of designs. Although I have shown the disk as circular in outline, it may be made polygonal to varyv its appearance when fluted.

. In Fig. 3 is shown the simplest form of the device in whichthe body portion is in the form of a plain, circular disk 16 having a central opening 17 and a radial slot 18 communicating with said opening. This slot permits the device to be mounted on a lamp bulb without removing the bulb from its socket. Although-the fluted form of device may be provided with a 'radial slot, it is preferable not .to do so because the slot isapt to spoil the set and appearance of the fluted form on the'lamp, and it is preferable in mounting it thereon to remove the lamp from its socket, adjust the device in position and then replace the bulb.

My devicemay be'madeof any material, such as'paper of various kinds or fabricsjor any material which is sufficiently absorbent to contain an appreciable amount of the vaporizable material but the paper or other material, must have sufficient body so that it will remain stifi and not collapse when it is impregnated with the vaporizable substance. I have found a filter paper of suflicient thickness to maintain its form when impregnated with vaporizable substance suitable for this use but it is evident that there are various other materials that can be used.

For impregnating the body portion, various vaporizablecompoun'ds may be used and one such which I have found satisfactory comprises a mixture of 50% denatured alcohol and 50% 'of any disinfectingmedicinal or odorizing oil soluble in alcohol. desired, oil of rose geranium may be used; if a medicinal odor is wished, then oil of eucalyptus disinfecting, then oil of creosote or other disinfecting oils may be employed. If a more saturated compound is desired, the proportion of oil to alcohol may be increased. It is to be understood, however, that my invention is not to be limited to the use of those oils soluble in alcohol 100 since any vaporizable material may be employed which is suitable for impregnating'devices made in accordance with my invention.

To impregnate the body portion withthe vaporizable compound it is dipped inuthe solution and allowed to' remain there until ithas become saturated, when it is taken out and partially dried by the evaporation of the alcohol, after which it may be packed either inglass' jars or in air tight cellophane wrappers in order to prevent further For instance, if a fragrant odor is of distinct advantages. whichis pure. and is not mixedwith the fumes influence of heat the device gives off the fumes i very rapidly and will impregnate the atmosphere of an ordinary room in a very few minutes.

In using the device on an electric light bulb, the heat radiated from the lamp when it is turned on will diffuse the fumes throughout avroom very quickly and a device impregnated according to the formula above noted will continue to give out an odor for some fifteen or twenty minutes. When a device of fluted electric lamp bulb, the heat radiated from the lamp causes currents of air to passupwardly between the lamp and out at thetop of the device in the openings formed by the fiutings which facilitates the impregnating of the atmosphere ,of a room with the'fumes and causes them to be rapidly distributed therein. r

.The device of my invention possesses a number It produces an odor of combustion which accompanies vapor pro- 'duced by the burning of aforeignmaterial with the substance to be vaporized. It is economical because all of the active material there is. no waste and the amount of the vaporizable agent inthe device may be variedto suit different needsor different spaces. Furthermore, it is of great convenience because it is easily put in use and-When it. has served its-purposa it is as easily removed. Lastly,.it is of, very.- low cost and can be soldat a low price.

. It is tobe understood'that my.- invention is not to be limited to the forms herein shown anddescribed since it may be embodiedin. various other formswithin the scope of the invention and the. purview of the following claims.

What I claim is:

material, said sheet having a flaring portion, and a central opening adapted to receive the neck portion of an electric lamp tion extending outwardly and projecting annubulb, said flaring porlarly to provide a substantial area adapted to V overhang the outer periphery of the bulb thereby affording an extended heat exposed surface.

2. A vaporizing device of the character described comprising a fluted member of paper or other absorbent material impregnated with a vaporizable material, said member being provided with an opening to receive the neck portion of an electric lamp bulb, the member overhanging the remainder of the bulb providing channels between the same and the bulb for the circulation of air.
